LITTER-CARRIER.

To all whom it may concern:

Be it known that I, OANUTE C. LAWSON, a citizen of the United States,residing at Skyberg, in the county of Goodhue and State of Minnesota,have invented certain new and useful Improvements in Litter-Carriers, ofwhich the following is a specification.

This invention relates to certain new and useful improvements in littercarriers.

The object of my invention is, to provide a light, simply constructedand readily operated carrier, arranged to be used in con veying manure,and like litter from a barn, sty, or other building, used in housinglive stock, so that the litter may be conveniently transported upon anaerial tramway, to a suitable dumping point, where the bucket or carrierwill be automatically dumped.

With these and other objects in view, the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described and particularly pointed out in the appended claim, itbeing understood that changes in the specific structure shown anddescribed may be made within the scope of the claim without de-. partingfrom the spirit of the invention.

In the drawings forming a part of this specification, and in which likenumerals of reference indicate similar parts in the several views,Figure 1 is an elevational view of a barn equipped with my improvedcarrier. Fig. 2 shows an enlarged detached detail of the trip as used inmy invention. Fig. 3 shows an enlarged detached detail of a modificationof my carrier frame. Fig. 4 shows an enlarged detached detail of thetension adjuster. Fig. 5 is a broken detached view of the bucketdisclosing the plate arranged to receive the lower end of the pivotedtrolley arm as used in my invention. Fig. 6 is a perspective view of theyoke receiving the spring holding the trolley arm. Fig. 7 shows an endview of my carrier.

In the care of live stock, such as cattle, horses, hogs, and poultry, itis quite necessary in order to keep the animals in good health that thehousing quarters be kept in a sanitary condition. In my present inven- Ttion, I provide a light portable, readily operated carrier, constructedso that the litter may be conveniently transported from the stablingpoint, to a suitable dumping point.

In the accompanying drawings, 5 shows a v barn equipped with my selfdumping carrier. The support for the carrier comprises Specification ofLetters Patent.

an aerial tramway, which in the building may comprise a stiff supportingrail, but whlch outside of the building is in the form of a cable 6.This cable is secured to a tension device comprising the yoke 7, havingits end held within the plate '8, which is carried upon the bolt 9, theyoke being adjusted by means of a nut 10. The bolt 9 is held within asuitable terminal supporting post as the one marked 11 and disclosed inFig. 1. The cable by means of this tension device may at all times beheld substantially taut.

The bucket or carrier, comprises a preferably sheet metal receptacle 14,of any suitable capacity, provided near its opposite lower edges withthe pivot bolts 15, which pass entirely through the bucket. These boltscarry the disk 16, and are secured within the sleeve end 17 of thecarrier frame 18. This frame may be in the form of a three sided member,or be curved if desired. Near its upper end the carrier frame hassecured to it the brackets 19, 19 carrying the cable sheaves 20,arranged to run upon the cable 6. .The frame is strengthened by means ofa corner brace 21, as shown. The bucket or carrier 14, near one end isprovided with the plate 22, having the slot 23 as disclosed in Fig. 5.The carrier frame 18 upon the side opposite the brace 21 is providedwith the pivot bolt 24 which pivotally supports the trolley arm 25 asdisclosed in Fig. 8. This trolley arm 25 has its lower end extendingoutward to form a keeper 26 which is arranged to work into the slot 23of the receptacle 14. In order to properly hold the lower end of thetrolley arm 25, I employ the bar 27 which forms a bracket so that thekeeper or detent 26 is held between this bracket 27 and the frame member18. The upper end of the trolley arm 25, extends beyond the upper end ofthe carrier frame 18 and is provided with a pin 28 revolubly supportingthe grooved wheel 29 arranged to work against the under surface of thesupporting cable 6.

At a suitable point above the pivot pin 24 the carrier frame 18 isprovided with the bolt 30, carrying the shackle 31 to which is secured asplit ring 32, this split ring receiving the end of a retractile coilspring 33, the lower or opposite end 34 of this spring being hooked tothe upper looped end of the yoke 35 as clearly disclosed in Fig. 8. Thisyoke 35 is secured to the trolley arm by means of the bolt 36. In Fig. 6I have disjump off the cable, it will strike this stop ear This stop earis and be held by the same. secured by means of the bolt 37. Theinstrumentalities are so arranged that in its 'normal condition thetrolley arm 25 will have its trolley wheel 29 riding against the cable 6while the lower keeper end 26 will be held within the bucket slot 23.

Secured to the cable 6 is a trip in the form of a bar 38 having theflaring terminal cars 39 and arranged to stride the cable 6. The trip 38carries the two screws l0 and these screws in turn support the clampingbars 41 which are slightly curved so as to clamp about the cable 6. Thetrip 38 is adjustably secured with the cable 6 by means of theseclamping bars 41, so that the trip may be located at any desired pointon the. cable.

The operation of my device is very simple. The bucket having been loadedis shifted along the aerial tramway until the trolley wheel 29encounters the trip 38. As the trolley wheel 29 rides upon the trip 38,the ends and positive in its operation.

And having thus described my said invention what I claim as new anddesire'to secure by United States LettersPatent is The herein describedconveyer, comprising a supporting cable, a trip adjustably secured tosaid cable, a carrier frame, support ing sheaves secured to said fran1e,and travelingupon said cable, a bucket pivotally secured tosaidcarrier'frame, said bucket hav- 111g a recelvlng slot, a trolley armpivotally secured to said carrier frame having its lower end arrangedfor engagement 3v1tl1m said slot, a trolley wheel secured to the upperend'of said arm and working against said cable, a yoke secured to saidtrolley arm, and

a spring secured to said carrier frame and said yoke.

In testimony whereof I afiiX my signature, in presence of two witnesses.CANUTE C. LAWVSON. VVit-nesses:
